In order to assemble into 4, it is only necessary to assemble the materials processed in the pre-cut factory for the joints and connections, so skill is not required. However, when the joist 106 is fixed on the pulling 105, the load to be applied is assumed. It is necessary to change the interval accordingly and fix it precisely, which requires the skill of a craftsman and takes time and effort. Roofs have similar drawbacks.

職人技により固定する必要はなく、単に下板を敷き詰め
ればよいので、現場での作業は簡易迅速に行なえる。こ
のため、工期を短縮できるとともに、技能者不足による
不都合を回避することもできる。The joints and connections of the erection materials are processed in a pre-cut factory, and it is not necessary to fix a large number of joists by craftsmanship as in the case of the conventional floor framing. Work on site can be done simply and quickly. For this reason, the construction period can be shortened, and inconvenience due to shortage of technicians can be avoided.

れば、その効果はより一そう高いものとなる。Further, a plate material serving as a rough floor in the case of a floor set or a roof underlining material in the case of a roof is constituted by a lower plate and an upper plate, and a spacer for forming these at predetermined intervals, that is, forming a space. Therefore, sound propagation is suppressed. In other words, the vibration transmitted to the upper plate is transmitted to the air in the space, but is absorbed and cut off in the space, and transmission to the lower plate is suppressed. For this reason, a floor combination greatly contributes to preventing floor noise. In particular, if a heat insulating material or a soundproofing material is loaded in the space, the effect will be even higher.

不要で、下板８の種類を少なくできる。Further, the lower plate 8 is not fixed so as to be placed on the upper surfaces of the base 5 and the pulley 6, but the corners of the lower plate 8 are
May be fixed so as to come into contact with the corners of the inside from the inside. In other words, as shown in FIG. 8, the upper surface of the large pulley 6 is not flush with the upper surface of the base 5, but the lower portion of the large pulley 6 is erected by the thickness of the lower plate 8. On the surface, a panel receiving member 19 which is flush with the upper surface of the pulling bar 6 is fixed.
And the puller 6 support the lower plate 8. With this configuration, the right-angled corner of the lower plate 8 comes into contact with the corner of the base 5 from the inside as shown in FIG. 9, so that the function of holding the base 5 at a right angle works. Thus, a solid structure can be obtained without separately fixing a blow as in the related art. In addition, it is not necessary to form the notch 8a for wiping the column 11 in a corner portion or the like of the lower plate 8 as in the case described above, and the type of the lower plate 8 can be reduced.

However, if there is a gap between the spacers 9 by fixing to the lower plate 8, the upper plate 10 Since it is easy for a load to be applied to the end of the lower plate 8, the lower plate 8 may be formed in a different shape. That is, this is the lower plate 8 as shown in FIG.
Are connected in the longitudinal direction, but as shown in FIG. 10, a separate joint plate 24 is formed so as to close the gap between the spacers 9 of each plate 8.
It is good to form in the shape except for. The edges of the joint plate 24 and the upper plate 10 are preferably set so as to abut on the spacer as much as possible.
